WinRAR - One of the best file compression tools around



WinRAR is a file compression application that is a must-have in any modern-day PC toolkit.
Compatible with all Windows
This application not only includes support for extracting virtually any kind of file compression format, it also reduces file sizes and runs on almost any version of Windows, from 98 to Windows 7. Besides, this version is compatible with both 32 and 64-bit systems.
Smaller files
Some will argue that WinRAR isn’t as quick as rival WinZip at compressing files. However, for the small time difference, WinRAR leaves you with a significantly smaller archived file at the end of the process. What’s more, the application allows you to save files into both .ZIP and .RAR formats, with loads of options for speeding up compression times and reducing file sizes.
Easy to use
Although many newcomers might be put off by the sheer range of features and settings within WinRAR, the interface doesn’t take long to get accustomed to. If you’re still really stuck, there’s a simple wizard-based system that walks you through the process of extracting or compressing. All this adds up to make WinRAR a dependable utility that performs better than any other tool in its class.
